Gangetic Loach Tank Setup

Give them at least 160 litres (42 US gallons) and a tight-fitting lid, since many loaches are escape artists. Keep the water at 66-81°F with a pH around 6-7.8; soft sand suits the ones that like to burrow. They reach about 20 cm as adults, so don't be misled by the small juveniles sold in stores.

What Do Gangetic Loaches Eat?

They're not fussy eaters - feed a varied diet, rotating good-quality dry, frozen, and gel foods rather than the same thing every day, and match the food size to their mouths.

Gangetic Loach Tank Mates

The Gangetic Loach is peaceful, which is the first thing to weigh up when you choose tank mates. At around 20 cm fully grown, it needs tank mates that can hold their own against its size and appetite. Before you buy, run your full stocking list through our stocking calculator. It weighs temperament, adult size, and water needs together, which a single species page can't do on its own.

Are Gangetic Loaches Good for Beginners?

Doable once you test water regularly and catch problems before fish look sick. If this is your first tank, pick something more forgiving and come back later.

Gangetic Loach - frequently asked questions

What size tank do Gangetic Loaches need?

Gangetic Loaches need a tank of at least 160 litres (42 US gallons). A bigger tank is always easier to keep stable, and gives them more room to settle in and behave naturally.

What water parameters do Gangetic Loaches need?

Keep them at 66-81°F with a pH of 6-7.8, steady rather than chased to an exact figure. In a cycled tank, ammonia and nitrite should both read 0 ppm, with nitrate kept low through regular water changes.

What do Gangetic Loaches eat?

Gangetic Loaches are omnivores and aren't fussy eaters. Feed a varied mix of good-quality dry, frozen, and gel foods, and match the food size to their mouths. Feed small amounts once or twice a day, and remove anything they don't eat.

Are Gangetic Loaches good for beginners?

Gangetic Loaches are best for keepers with a little experience. They are manageable once you test water regularly and catch problems early; a complete beginner may prefer something more forgiving first.

Common mistakes with Gangetic Loaches

  • Underestimating tank size - the minimum footprint is 160 litres (42 US gallons); impulse buying into a smaller tank leads to stress and shortened lifespan.
